FUNCTION
        <<strerror>>---convert error number to string
 
INDEX
        strerror
 
ANSI_SYNOPSIS
        #include <string.h>
        char *strerror(int <[errnum]>);
 
TRAD_SYNOPSIS
        #include <string.h>
        char *strerror(<[errnum]>)
        int <[errnum]>;
 
DESCRIPTION
<<strerror>> converts the error number <[errnum]> into a
string.  The value of <[errnum]> is usually a copy of <<errno>>.
If <<errnum>> is not a known error number, the result points to an
empty string.
 
This implementation of <<strerror>> prints out the following strings
for each of the values defined in `<<errno.h>>':
 
o+
o E2BIG
Arg list too long
 
o EACCES
Permission denied
 
o EADDRINUSE

RETURNS
This function returns a pointer to a string.  Your application must
not modify that string.
 
PORTABILITY
ANSI C requires <<strerror>>, but does not specify the strings used
for each error number.
 
Although this implementation of <<strerror>> is reentrant, ANSI C
declares that subsequent calls to <<strerror>> may overwrite the
result string; therefore portable code cannot depend on the reentrancy
of this subroutine.
 
This implementation of <<strerror>> provides for user-defined
extensibility.  <<errno.h>> defines <[__ELASTERROR]>, which can be
used as a base for user-defined error values.  If the user supplies a
routine named <<_user_strerror>>, and <[errnum]> passed to
<<strerror>> does not match any of the supported values,
<<_user_strerror>> is called with <[errnum]> as its argument.
 
<<_user_strerror>> takes one argument of type <[int]>, and returns a
character pointer.  If <[errnum]> is unknown to <<_user_strerror>>,
<<_user_strerror>> returns <[NULL]>.  The default <<_user_strerror>>
returns <[NULL]> for all input values.
 
<<strerror>> requires no supporting OS subroutines.

283			`PORTABILITY`
284			`ANSI C requires <<strerror>>, but does not specify the strings used`
285			`for each error number.`
286
287			`Although this implementation of <<strerror>> is reentrant, ANSI C`
288			`declares that subsequent calls to <<strerror>> may overwrite the`
289			`result string; therefore portable code cannot depend on the reentrancy`
290			`of this subroutine.`
291
292			`This implementation of <<strerror>> provides for user-defined`
293			`extensibility. <<errno.h>> defines <[__ELASTERROR]>, which can be`
294			`used as a base for user-defined error values. If the user supplies a`
295			`routine named <<_user_strerror>>, and <[errnum]> passed to`
296			`<<strerror>> does not match any of the supported values,`
297			`<<_user_strerror>> is called with <[errnum]> as its argument.`
298
299			`<<_user_strerror>> takes one argument of type <[int]>, and returns a`
300			`character pointer. If <[errnum]> is unknown to <<_user_strerror>>,`
301			`<<_user_strerror>> returns <[NULL]>. The default <<_user_strerror>>`
302			`returns <[NULL]> for all input values.`
